WIRE SPLICER.

Application filed March 10, 1927. Serial No. 174,189.

This invention relates to improvements in wire splicers and more especially to a manually operable, light, easily handled device of that character.

My improved wire splicer is neat, durable, easy and cheap to manufacture, and simple and efiicient in operation.

Other features and advantages of my invention will appear more fully as I proceed with my specilication.

In that form of device embodying the features of my invention, shown in theaccompanying drawings, Fig. 1 is a vertical sectional view, Fig. 2 is a view taken as indicated by the line 2 of Fig. 1, and Fig. 3 is a plan view showing the splice made by my improved device.

I haveshown in the drawings, the device comprising a suitable bifurcated frame 10,

carrying the cylindrical or drum shaped rotor 11 pivotally mounted between the jaws or prongs thereof on the trunnions 12 and having its periphery roughened or lrnurled Vas indicated by 13 to permit it to be rotated by the lingers.

The frame l0 is provided with a suitable extension 14: carrying the handle 15.

16, 16 indicate the overlapping ends of the wires to be spliced.

The rotor 11 is provided with a radial slot from its periphery to the center, said slot at the center, as indicated by 17 being substantially the diameter of the wire 16',

the remaining portion of said slot being somewhat wider as indicated by 17a. The

trunnions of the rotor l1 are bored out centrally as indicated by 18 from the end of each trunnion toward the center; but such bores do not meet. A short length of the central slot 17 is permitted to remain in the central part of the rotor to hold the middle parts of two overlapping portions of wire in the device.

Each of the jaws 10a, 1()a of the frame 10 is provided with a similar slot 10b having a width substantially equal to the diameter of the wire 16 and these slots are preferably widened somewhat at the top as indicated by 10c to facilitate the insertion of the wire.

The slots 10b are adapted to hold the ends of the overlapping portions of wires against rotation as the rotor is turned to twist the middle part-s of said overlapping portions about each other.

In the operation of the device, the overlapping ends of two wires are placed adjacent each other and inserted in the slot-s 10b and 17. The rotor l1 is then given three or four turns to twist the middle parts of the overlapping portions about each other, the ends of said overlapping portions being held against rotation by the slots 10b, 10b. This results in splicing the wires as shown in Fig. 3. The wires are then removed from the device.

It will be seen that in the use of my wire splicer, the two wires may be laid in the device as shown in Fig. 1 and the ends pulled in opposite direction to tighten the wire. When thus tightened the splice can be easily and readily made. In many cases, in connection with the splicing of wires, it is difficult to so make a splice while the wires are under tension. This can be very easily done, however, with my improved wire splicer.

The inner edges of the slots 101 in the jaws as indicated at 101 are preferably squared off sharply in order to make more or less of a cutting edge. It will be found then that after the splice is made that the short ends of the wires beyond the splice are given a rather sharp bend, indentation or cut where they are bent over this edge as indicated by 16h, permitting these ends to be very easily broken olf by a slight bend` ing of the wire at this point.

Vhile I have shown and described :ei'-v tain embodiments of my invention, it is to be understood that it is capable of many modifications. Changes, therefore, in the construction and arrangement may be made without departing from the spirit and scope of the invention as disclosed in the appended claim, in which it is my intention to claim all novelty inherent in my invention as broadly as possible in view of the prior art.

Vhat I claim as new, and desire to secure by Letters Patent, is:

A wire splicer comprising; a frame provided with two jaws, each having a slot of a width substantially equal to the diameter of a wire to be spliced; and a rotor supported between said jaws, having its axis substantially in line wit-l1 portions of the slots in said jaws, said rotor being provided with a. radial slot, the width of which at the inner end is substantially equal to the diameter of a wire to be spliced, the ends of the slot in the rotor being spaced from the inner ends of the slots in the jaws, the inner edges4 of the walls of the slot in the jaws being sharply squared to form cutting edges adapted to indent the projecting ends of the wires atthe ends of the splice.

ln witness whereof, I have hereunto set my hand this 7th day of March, A. D. 1927.
